To @ZZ whom t may concern.'

Be it known that I, GEORGE BARNETT, a citizen of the United States,residing at Louise, in the county of Wharton, State of Texas, haveinvented certain new and useful Improvements in Wheel-Flows; and I dohereby declare the following to be a full, clear, and exactdescriptionof the invention, such as will enable others skilled in the artto whichit appertains to make and use the same.

This invention relates to plows, and more particularly to wheel-plows,and has for its object to provide an implement of this kind which willbe arranged to permit .of independent vertical movement of certain ofits wheels to allow them-to pass easily over obstructions.

Another object is to provide a plow so arranged that certain of itswheels may be shifted to vary the angle of the share and which will beprovided with means for shifting the wheels.` Other objects andadvantages will be apparent from the following description.

In the drawings forming a portion of this specification, and in whichlike characters of reference indicate similar parts in the severalviews, Figure 1 is a side elevation ofthe present plow. Fig. 2 is a rearelevation. Fig. 3 is a vertical transverse section taken longitudinallyof the cross member. Fig; 4 is a top plan view. Fig. 5 is across-section of the cross member.

Referring now to the drawings, the present invention comprises a crossmember 5, including plates 6 and 7. A beam 9. is engaged between theinner ends of the plates 6 and 7 for sliding movement longitudinallythereof, and means 10is provided for holding the plates and beams atdifferent points of their movement with respect to each other.

Vertical guides 11 arecarried by the member 5 at its ends, one beingsecured between the plates 6 and 7 and the other to the beam 9, andreceived slidably within the guides are vertically-disposed U-shapedslides 12, the bights 13 of which are directed upwardly. Rollers 14 aredisposed in the guides between the legs of the U-shaped slides and restagainst the legs thereof, the slides being thus arranged for easyvertical movement. Vertically-extending sprocket-wheels 15 are pivotallymounted upon the bights 13, and sprocket-chains 16 are secured at oneend to the guides 11 at the inner portions thereof,

passing upwardly and over -the sprockets 15 .and then downwardly andunder the sprockets 17, loc-ated adjacent to the lower ends of theguides, the chains passing inwardly from these last-named sprockets andbeing secured to helical springs 18, which are attached to the crossmember 5. These vsprings thus hold the slides yieldably against upwardmovement.

Outwardly-projecting horizontal spindles 19 are carried by the lowerends of the slides, which extend beneath the member 5, and journaledupon these spindles are groundwheels 20, these wheels `being arrangedfor independent vertical movement, as will be apparent from theforegoing.

Pivotally mounted upon the beam 5 for horizontal movement with respectthereto there is a casting 21, which is located adj acent to one end ofthe beam, this casting being held in position by a bolt 22, pivotallyengaged therein and passed through a plate 8, located beneath the plates6 and 7 and turned upwardly against the outer faces thereof.

Amain plow-beam 23 is secured in the casting 21, thus extendingtransversely of the member 5 andlongitudinally of the implement, therearward end of this beambelng .turned downwardly and has securedthereto plate 29, secured at itsrearward end to the plow-beam, andthusforming a frame to which is pivoted a vertically-extending lever 3.0,means 31 being provided to hold the lever at dierent points of itsmovement. The lever extends above and below its pivotpoint and at itslower end is connected by means of a forwardly-extending link 31, towhich the member 5 is connected adjacent to one of its ends, and a link32 extends rearwardly from the lower end of the lever 30 and isconnected with the arm 26. It will 'thus be apparent that the lever 30may be IOO at which the share enters the ground, and the arrangement ofthe arm 26 and link 32 is such that the wheel 28 is shifted with thewheels 20 to occupy at all times a plane parallel with those of thelast-named Wheels.

A cOlter-wheel 3 3 is located forwardly of the share 24:.

A member 34 extends vertically and is connected with the beam 2 3forwardly of the member 5 for sliding vertical movement with respectthereto. A rearwardly-extending lever 35 is pivoted upon a bracket A,carried by the beam, and has a forwardly-extending arm 36, bifurcated atits forward end, and having a vertical roller 37 engaged in itsbifurcation, this roller being carried by the upper end of the member34. Means 38 is provided for holding the lever 35 at different points ofits movement, and at its lower end the member 34 has a wheel 39revolubly connected therewith and disposed to rest upon the ground, thewheel being movable vertically with the member, as will be readilyunderstood, and varies depth of share.

rhe beam has a clevis 40 at its forward en What is claimed is- 1. Animplement of the class described, the combination with a beam, of across member connected therewith for horizontal pivotal movement,vertical guides carried by the ends of the member, slides in the guides,flexible members connected with the firstnamed member, rollers'pivotedupon the slides, said flexible members being engaged '3. In an implementof the class described, the combination with a beam, of a castingengaged with the beam, a member pivoted to the casting ,forI horizontalmovement, wheels carried by the member, a laterallyextending bar carriedby the casting, a frame engaged with the bar and secured to the beam, alever pivoted upon the frame, and connections between the lever and themember for movement of the member upon its pivot when the lever ismoved.

4. In an implement of the class described, the combination with a beam,of a casting engaged with the beam, a member pivoted to the casting forhorizontal movement, wheels carried by the member, a laterallyextendingbar carried by the casting, a frame engaged with the bar and secured tothe beam, a lever pivoted upon the frame, a wheel pivotally connectedwith the beam for lateral movement, a link connected with the wheelandwith the pivoted member, said lever being pivoted to the link formovement thereof to shift the wheel and member when the lever is moved.

5. In an implement of the class described, the combination with a beam,of a transverse member pivoted to the beam for horizontal movement,vertical guides carried by the ends of the transverse member, rollerslO- cated in the guides, U-shapedy slides having their bights directedupwardly engaged in the guides with their legs at Opposite sides of therollers, spindles engaged in the lower ends Of the legs, wheels mountedupon the spindles, sprockets carried by the bights Of the slides, chainshaving fixed ends engaged over the sprockets, andV springs secured tothe member and connected with the chains to hold the latter yieldablywith the slides against upward movement.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE w. BARNETT.
